Chemical Biology 3OA3, September 2009 Page 7 SAFETY IN LABORATORY OPERATIONS 1. Accidents occur every year from the careless handling of glassware. These result in considerable inconvenience and loss of time. These kinds of accidents could be avoided if the following rules are observed. (a) Before inserting a thermometer or glass tube into a stopper or rubber tube: i) Be certain the hole is large enough to accommodate the glass. ii) Lubricate the glass and the rubber with glycerol or stopcock grease. iii) Protect your hands by holding the stopper and the glass in towels. Hold the stopper by your fingers NOT IN THE PALM OF YOUR HAND. iv) Grasp the glass close to the end that is to fit into the stopper and twist with an even pressure. (b) Do not attempt to push or pull glass tubing or thermometers from rubber tubing, corks or stoppers which have become hardened. Cut the rubber or cork from the glass. (c) Fire-polish the ends of all glass tubing and glass rods.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
